Tiny front pocket ---on your jeans---why?

what is the purpose of having a tiny front pocket on your jean? Have your thought about it? Many times, I thought of making a question. But, was not may be due not having the time or due to something more serious than a discussion on this . Whatever it may be. This tiny pocket is actually meant for keeping a watch. In 1800 the cowboys were keeping their pocket around this area and tucking their watch in this pocket.
Though, nowadays we are not putting a watch in it is used or termed as Condom pocket, coin pocket or Ticket Pocket. If you can not put a ticket then you can put the small change in it.
